To provide an electrically-driven actuator capable of surely actuating a reverse input retention mechanism and reducing costs; and to provide an electric brake device.SOLUTION: A control device 2 for the electrically-driven actuator comprises: motor angle estimation means 22a; and a reverse input retention control part 24 with a function for setting a parking brake mechanism 7 to be in a reverse input retention state by engaging an engaging part 15 with an engaged part by controlling a solenoid 16 in a state in which the electrically-driven actuator DA exerts a load, and a function for setting the parking brake mechanism 7 to be in a reverse input retention releasing state by disengaging the engaging part 15 from the engaged part from the reverse input retention state. The reverse input retention control part 24 has an engagement intermediate control function part 24a for controlling a rotational angle to be estimated for the engaged part and the engaging part 15 to have a predetermined positional relation when the engaged part and the engaging part 15 are engaged with each other and when the engaging part 15 is disengaged from the engaged part.SELECTED DRAWING: Figure 4

    【課題】逆入力保持機構を確実に動作させることができ、かつコスト低減を図ることができる電動式アクチュエータおよび電動ブレーキ装置を提供する。【解決手段】この電動式アクチュエータの制御装置2は、モータ角度推定手段22aと、電動式アクチュエータDAが負荷を発揮している状態でソレノイド16の制御により、被係合部に係合部15を係合させてパーキングブレーキ機構7を逆入力保持状態とする機能、および逆入力保持状態から前記被係合部に対し係合部15を離脱させてパーキングブレーキ機構7を逆入力保持解除状態とする機能を有する逆入力保持制御部24とを備える。逆入力保持制御部24は、被係合部に係合部15を係合させるときおよび被係合部に対し係合部15を離脱させるとき、一定時間内に被係合部と係合部15とが定められた位置関係となるように、推定される回転角度を制御する係合中間制御機能部24aを有する。【選択図】図4
